The system ROM contains the POST (power-on self-test) routines, and the BIOS: the System BIOS, video BIOS, and Intel LAN boot ROM. The system BIOS is identified by the version number JH.01.yy. The latest BIOS version for your PC and instructions for updating the BIOS can be downloaded from the support Web site at: www.hp.com/go/support.
BIOS Overview Using the PC Setup Program In the Configuration and Diagnostics menu press F2 to run the Setup program. The Setup screen comprises six menus: Main, Advanced, Security, Boot, Power and Exit. These are selected using the left and right arrow keys. A list of the menus and submenus in the Setup screen is given below. See Setup Help for a description of each field.
BIOS Overview Boot Menu The Boot menu is comprised of the following fields: • Quick Boot Mode • Boot-Time Diagnostic Screen • Display Option ROM Message • Boot on LAN after RPO • Boot Device Priority Power Menu The Power menu is comprised of the following fields: • State After Power Failure • Power-up on PCI Bus Activity • Advanced Power Management Exit Menu The Exit menu is comprised of the following fields: • Exit Saving Changed • Exit Without Saving Changes • Load Default Settings
BIOS Overview Power Management and Wake Up Events You can reduce the PC’s overall power consumption by using Power Management to slow down the PC’s activity when it is idle. ACPI Power Management Modes (Windows 98, Windows 2000 and Windows XP) • Idle (s1): The processor is shutdown. • Standby (s3): All components of the system are shut down except for the system memory which remains active. This management mode is also known as “Suspend to RAM”.

BIOS Overview HP e-DiagTools Preboot Diagnostics (Beep Codes) When your PC starts up, its BIOS performs a Power-on Self Test (POST) to test your hardware configuration for any problems. If a problem is detected during the POST, an error is displayed on your PC’s monitor. If, however, your PC is unable to display an error message (for example, when your graphics controller has failed), it will emit a buzzing sound. This is the e-DiagTools preboot diagnostic.
